There's a You tube video on rebuilding VTX 1800 forks. They are the same design internally. You would benefit from buying a factory service manual.

You might want to read a couple of posts about cleaning leaky seals first. I had a leaky right side fork seal, bought a Seal Mate (others prefer Seal Doctor) on the advice of forum members and voila, no more leaky! That was over four years ago.

And, pay the extra money for Honda seals instead of All Balls. The All Balls just don't fit right. As mentioned, get a service manual and get to it. The special tools needed can be found on ebay for cheap.

No special tools needed if you leave the forks on the bike and just replace seals. Total novice here. I took my time, did one side at a time, and had very little trouble.

Although I removed the forks from the bike to do mine, the one "special" tool you will need is a wrench slim enough to loosen/tighten the lock nut (#19) at the top of the right fork. I found none of mine were slim enough, but then discovered the wrench in the OEM tool kit worked. The videos Sandy mentioned were really helpful to me. Just search "vtx 1800 fork seals" on YouTube and watch the four-part series by "brochscheller".  |

Another Tech thread got me down a forking rabbit hole, and this one is timely.
Looking at Find #7 in the diagram above...Tube (Outer) on the Valkyrie 'fiche shows as unavailable.
The VTX1800 part, on the other hand, is still listed. I'm pretty certain they're equal in length and in diameter, though someone with both bikes on-hand might verify this.
The internals are another matter. Several different dampers and rods (right and left fork tubes, respectively) are listed. Having owned and ridden an 1800-C, they're a heavy bike. Moreso the -S, -R and -N variants. Some of these models still list the fork internals as being available.
The question to the board at large: Has anyone played with various dampers in their forks to see how the ride is altered? Or is the better solution to hit Traxxion Dynamics up for a complete set of internals, should one wish to change the loading/damping characteristics?

Thanks for the help. I want to the replace just the seals without removing the forks from top tree and messing with the springs. Do I need and special tools to do it this way and how do I add new oil?

IMHO, you will want/need two good torque wrenches, a 45mm seal driver, a means to measure out fractional ounces of fork oil, a steady and relatively high motorcycle jack, plus all the needed sockets and allen head wrenches.
You definitely will want to have the info on torques, oil amounts, and reassembly order that is in the repair manual and is generally available in some of the archives.

The extra trouble to remove the forks from the triple tree is not that much, and it helps to completely drain the old oil. Better to buy or download a shop manual rather than rely on us remembering and typing out the "how to" information on this. Also watch the YouTube videos I mentioned. There are two methods to know how much oil to add. One involves removing the springs, requiring a special tool you can buy or make, then measuring a specific distance down to the oil level, and the other requires completely draining the old oil and precisely measuring how much new oil you put in. I bought a graduated cylinder from a scientific supply company to use the second method. A special tool that I forgot about earlier that is required, is a fork seal driver. I made one from PVC pipe. |
